Political protesters shouted down Gov. Scott Walker Thursday as he officially declared the fair open for business.

From the moment Walker stepped on stage for the State Fair opening ceremony, a group of protesters in the crowd tried to shout him down.

But Walker carried on, trying not to let it interfere with his message, or the fair itself.

"Eight hundred thousand people are going to be here this week, and that handful of people will not distract the majority. People from around the state and around the Midwest are going to come and have a fun time," Walker said.

There was a also a strong showing of Walker supporters in the crowd, but they appeared outnumbered and outshouted by the anti-Walker protesters.

The governor has become accustomed to seeing protesters but questioned why people would do that at the fair.

"It's one of those things people have a right to do. Most people come to the fair, and they set aside politics and business and just have a good time," Walker said.

The protesters did not let up, and so as many in the crowd called for his recall, the governor continued on and did what he came to do.

"We declare the 2011 Wisconsin State Fair open for business," Walker said.

Other than the chanting during the governor's address, the ceremony went off without incident.

The governor is expected to return for the governor's auction next week.
